Abstract
A corporeal access tube assembly includes a tube segment containing a coil spring. A retention balloon is secured to the tube segment around a portion of the segment. A deflation lumen extends through the tube segment from a predetermined location in said tube segment which is spaced from one end of the tube segment to a location adjacent the balloon where it is in fluid communication with the balloon. A set connector has a fitting with external threads which is threaded into the one end of the tube segment and into the coil spring.
